Hi Marcelo,
I think, iRacing is associated with present-day Racing ... and present-day ads on present-day cars do make it even more realistic.
But GT-Legends is dedicated to the racing of the 1960's, 70's (and 80's). Most of the ads shown on the cars go back to historic Teams, such as the Martini or Gulf Designs and the Decals placed by Sponsors of these past days.
Whatsoever, there may be a way, to place at lesat some advertisement on ABB trough planning events, Modding or Trackdesign.
Look at the "Car-Release" Notifications ... "Brickyard legends Team" is a common sight for all of us ... and thats what ads are supposed to do, placing a "companys name" in the head of the people
I don't know, which company we are talking about, but imagine a Race-Series going on for years (as the ABB-ETCC did), called "Music-xpress Campionship", with your companys logo on each and every notification related to that series ... including vids of the races on your companys YT-Channel ...
If you designed a new Track, I don't think anyone would complain about a few ads more or less, as long as they don't kill the realistic feel of the track (imagine the 1975 Nordschleife with ads by jobscout24.de or google ... doesn't add up well).
I'm not to decide, and I don't even know, if such ideas are appreciated by the admins.
I just wanted to tell you, that there is more than skin-design.
Regards
Olaf
